The MessageSigner type exposes the following members.

Constructors

	Name	Description
	MessageSigner(X509Certificate2)	Initializes a new instance of the MessageSigner class from signer certificate and default hash algorithm. Default hash algorithm is SHA256.
	MessageSigner(X509Certificate2, Oid2)	Initializes a new instance of the MessageSigner class from signer certificate and client-provided hash algorithm.

Properties

	Name	Description
	HashingAlgorithm	Gets or sets the hashing algorithm that is used to calculate the hash during signing or signature verification processes.
	PaddingScheme	Gets or sets signature padding scheme for RSA signature creation and validation. Default is PKCS1.
	PssSaltByteCount	Gets or sets the size, in bytes, of the random salt to use for the PSS padding. Default value matches the hash output length: 16 bytes for MD5, 20 bytes for SHA1, 32 bytes for SHA256, 48 bytes for SHA384 and 64 bytes for SHA512 hashing algorithm.
	PublicKeyAlgorithm	Gets public key algorithm.
	SignatureAlgorithm	Gets resulting signature algorithm identifier.
	SignerCertificate	Gets the certificate associated with the current instance of MessageSigner.

Methods

	Name	Description
	Dispose	Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Overrides ObjectFinalize.)
	GetAlgorithmIdentifier	Gets ASN-encoded algorithm identifier based on current configuration.
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	SignData	Signs the data with signer's private key and specified hash algorithm.
	SignHash	Signs the hash with signer's private key.
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	VerifyData(Byte, Byte)	Verifies that the specified signature matches the specified hash.
	VerifyData(SignedContentBlob, PublicKey)	Verifies signature of a signed blob by using specified public key.
	VerifyHash	Verifies that the specified signature matches the specified hash.

Remarks

This class implements IDisposable interface. It is recommended to wrap this class in using statement to automatically release unmanaged resources during signing procedure.
